Chewing gum as a means of keeping teeth strong

Osteoporosis is a condition in which bones become progressively thin, brittle and frail.  Most of us are probably well aware that osteoporosis can be a debilitating or even crippling.  Exercise, especially weight-bearing exercise, builds bone and protects against osteoporosis and frailty later in life.  Unfortunately, only bone under stress seems to benefit.  For example, runners, who carry their own body weight, tend to have stronger leg bones than cyclists.

Osteoporosis and teeth: keeping teeth strong

Fewer may be aware that osteoporosis can affect the condition of our teeth too.   Osteoporosis can cause thinning of the bone material anchoring teeth.   Keeping teeth strong may help prevent tooth loss and other dental problems.

Can exercise help in keeping teeth strong and health?

There is some evidence that exercise can improve or protect dental health.  The only study found in a literature search of Web Of Knowledge saw less tooth loss among older Japanese men who exercised daily (Yoshida et al. 2001.)  This doesn’t quite tell us enough, because of other variables that are also associated with more or less tooth loss such as hygiene, frequency of professional care, dietary habits and smoking. The study did not look at any exercise that might specifically target facial bone or jaw muscles.  Few forms of exercise will target the bones or muscles that support our teeth (although some do manage to make an exception here.  Look around and check facial expressions during heavy lifts).  Still, the study indicates that exercise may help protect against tooth loss or weakness. It is important that jaw and facial bones stay healthy.  If they degrade they will not be able to hold onto your teeth.  Unfortunately, there has been very little research on exercise and tooth loss.

Is chewing gum good exercise for the bones supporting teeth?

Chewing gum good for teeth.  Experienced as Hell Tank Masters Athletes Protein Chewing gum may strengthen jaw bones and could protect chewers from tooth loss or improve the outcome of periodontal disease by providing exercise.  Little work has been done in this area.  The only chewing gum-specific study I could find was by a research team in Russia who studied the effect of chewing gum on bone density in 93 periodontal patients (Loginova et al. 2006.) Bone density in these patients increased on the active chewing side.   For optimal effect make sure to switch your gum from right to left periodically.  Goes for the rest of your training too. The full paper is available in Russian.

Is Chewing Gum Good for Teeth? Exercise and gum may protect your jaws and prevent tooth loss.

Exercise, especially weight-bearing exercise, builds bone and protects against osteoporosis and frailty later in life.  Unfortunately, only bone under stress seems to benefit.  For example, runners, who carry their own body weight, tend to have stronger leg bones than cyclists.  Crossfit provides excellent training for bone strength.  It includes weighted movements that target, stress and should strengthen most of the bones in the human body.  That is provided you don’t over train and damage them or have an accident (see post on the risks and benefits of box jumps.)

Exercise may help protect against tooth loss or weakness.

One area that weight lifting and most forms of exercise will not target are the bones that make up our jaws (although some do manage to make an exception here.  Look around and check facial expressions during heavy lifts).  It is important that these bones stay healthy.  If they degrade they will not be able to hold onto your teeth.  Unfortunately, there has been very little research on exercise and tooth loss.  The only study found in a literature search of Web Of Knowledge saw less tooth loss among older Japanese men who exercised daily (Yoshida et al. 2001.)  This doesn’t quite tell us enough, because of other variables that are also associated with more or less tooth loss such as hygiene, frequency of professional care, dietary habits and smoking.

Vitamin K may keep your brain from falling apart

Keeping your brain from falling apart is serious business.  Tape and twine have their places, but we are writing to report on some other . . . . “stuff.”   Today’s stuff is Vitamin K.

Vitamin K, Health and Research

Research is indicating that Vitamin K may be important in protecting brain function. Researchers recently measured vitamin K levels in blood (as serum phylloquinone) and compared them with how well people did on several tests of cognitive function. People with higher levels of Vitamin K did better on tests of verbal memory and recall.   320 men and women between the ages of 70 and 85 participated in the study. This is good news because we do have some control over our vitamin K intake. The study has its limitations of course.  A blood test measures only what is currently in a person’s system.    The blood test used in this study was not able to measure people’s Vitamin K intake over a long period of time.

What is Vitamin K?

Vitamin K is a fat soluble vitamin.  There are two common forms K1 and K2.  K1 comes from plants.   K1 was the form of vitamin K evaluated on the study of cognitive function.

Animals (like us) use K1 to make K2.  K2 is also synthesized by bacteria in the gut.   People may have many different kinds of gut bacteria.  Your gut bacteria will be influenced by your diet and medical history.

Vitamin K is best known as the vitamin the helps blood clot.  Good dietary sources of Vitamin K include:

  • Leafy greens
  • Brussels sprouts, cabbage, cauliflower, broccoli
  • Grains (minor sources)
  • Liver, eggs, meat, fish

Vitamin K may be important for maintaining bone health as well as brain health.  Vitamin K is being evaluated as a possible treatment for osteoporosis.  Until we hear more on that it is probably best to eat real food and plenty of vegetables rather rely on supplements.  Vitamins in vegetables come “packaged” with many other biologically important molecules.  You may need the entire package (by which we mean vegetable not multivitamin).  A dose of one particular molecule may not be particularly helpful.

Bone Health and Osteoporosis: Ups and Downs of Bisphosphonates.

Bone Health and Osteoporosis Risks

CrossFit Bone Health and Osteoporosis.
A CrossFit Masters Athlete from CrossFit Bare Cove in Hingham, MA. takes care of her Bone Health.

If you are young you should eat well, not smoke, and get plenty of weight bearing exercise. Preferably starting from birth (which would be moving your little arms and legs.) There is a lot of research going on in Bone Health. We are learning about it at a rapid rate. This is exciting, but it also means there is a lot that is unknown. And our understanding may change. So far, the agreed Major risk factors for Osteoporosis include:

  • Being female (women lose bone at faster rates than men, and have less to start with)
  • Being white
  • Being small-boned
  • Smoking
  • Drinking
  • Poor nutrition
  • Sedentary lifestyle
  • Losing weight
  • Menopause

Bone Health Protection

  • Being black
  • Having a larger frame
  • Gaining weight (but can cause other health problems)
  • Good diet, not smoking, minimal alcohol intake
  • Weight bearing exercise
  • Being on hormone replacement therapy for menopause (but this increases risk of heart disease and breast cancer)
  • Sufficient vitamin D
  • Sufficient calcium intake

Some things are within our control.  Others are not.  If you are having bone loss you should consider taking bisphosphonates.

 

Bone Health and Bisphosphonates

Bisphosphonates are drugs used to prevent osteoporosis (excessive bone loss). Bone is living tissue. It is constantly replenishing and remodeling itself. Visualize a busy sculptor with modelling clay. If your body (sculptor) senses that bone is not under much stress it will stop paying so much attention to it and focus its energies somewhere else. Bisphosphonates block the cells that break down bone. Cells that produce bone are not bothered by bisphosphonates. This leads to thicker bones.

Bisphosphonates can make bone thicker, reducing hip fractures. They can also make bone more brittle. Some people who have been on bisphosphonates have suffered peculiar shattering of bones. Hip fractures are very dangerous, whether you have osteoporosis. Especially for older people who do not heal as quickly as young people. If you are over age 50 there is a 25% chance that a hip fracture will kill. The odds are worse for the elderly and frail. If you are thinking of taking a bisphosphonate drug to prevent osteoporosis you should probably think about the odds of getting a “traditional” hip fracture vs. a bisphosphonate fracture. The odds of getting a bisphosphonate-type fracture are quite small compared to the risk of getting a traditional hip fracture. Easy choice?  Not yet.

Bisphosphonates and other health risks and benefits.

Bisphophonates may improve “bone health”. They are also associated with

  • Cancer of the Esophogus
  • Atrial Fibrillation (this seems to be more of a risk with intravenous administration)
  • Decreased risk of colorectal cancer (Yea!)
  • Decreased risk of stroke. (Yea)
  • Disintegration of the jaw and tooth problems.
  • Making you feel crappy.   If you take bisphosphonates you should sit quietly for 30-60 minutes afterward.  This will reduce the risk of damage to the esophogus.

Bone Health, Bisphosphonates and Duration of Treatment

Your doctor may recommend that you take bisphosphonates for several years (maybe 5) and then stop for a year or two.  You would be monitored during your “vacation” time to see if your bone has stabilized.  If you start to lose bone again, your doctor may put you back on bisphosphonates.

Meanwhile, continue to eat well and exercise.  Think about giving CrossFit a try too.

I hope this helps.
